Abstract

The invention discloses a pressure detection display device which includes a substrate, a first semiconductor layer which is provided with a plurality of pressure detection induction units, an insulating layer which covers the first semiconductor layer, a pressure-sensitive detection circuit which is used for providing an input voltage signal for the pressure detection induction units and receiving pressure induction signals collected by the pressure detection induction units, and electrostatic protection rings of which the orthographic projections on the substrate are closed rings, wherein the orthographic projection of each pressure detection induction unit on the substrate is within one of the closed rings. According to the scheme of the invention, an electrostatic protection effect is achieved for the pressure detection induction units, and damage to the pressure detection induction units caused by the accumulation of static charges introduced by the subsequent process in the pressure detection induction units is avoided.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, to a pressure detection display device. Background technique [0002] With the development of display technology, only touch position detection can no longer meet the diverse requirements of the interactive operation modes of the human-computer interaction interface presented on the display screen. In addition to detecting the coordinate position of the finger on the display screen plane, it is also necessary to detect the pressure of the finger pressing the display screen, so as to perform corresponding display according to the difference in pressure. [0003] The design of the pressure sensing function in the existing display screen mainly adopts capacitive or resistive pressure sensors. In the design of resistive pressure sensors, in order to avoid affecting the light transmittance of the display area, multiple pressure sensors are usually arranged in th...
